I have small problem to print float value in the fallowing code
I am trying to print Cx value using above code but it was not printing like that, the value i am getting when i tried to print Cx value using above code is 7.077140 . I am getting of 6 digit precision value only. How to get 10 digit precision value or how to print like this 7.07E-9.
I am trying to compare 2 float values using if
the foll code does not work
a=1.4
b=1.6
if test $a -gt $b
then
echo "$a is max"
else
echo "$b is max"
fi
does -gt work for floating point numbers, if not how do go about for my requirement? can i use bc ? pls help
thanks in advance... (2 Replies)
Hi
I know its a dumb question but can any one please explain me the difference of executing a shell script in the following 2 ways.
. script.sh
sh script.sh

Good morning,
I'm testing the use of ceilf:
/*Filename: str.c*/
#include <stdio.h>
#include <math.h>
int main (void)
{
float ceilf(float x);
int dev=3, result=0;
float tmp = 3.444f;
printf("Result: %f\n",ceilf(tmp));
return 0;

Today I spent longer than I'd like to admit figuring out how to write a Bourne shell IF statement that tests a FLOAT value before executing a block of statements. Here's the solution I found, which invokes bc. Hope this will come in handy for someone:
value =
testval =

Hello!
I'm making an English to Morse Code translator and I was able to mostly get it all working by looking through older posts here; however, I have one small problem.
When I run it it's just printing spaces for where the characters should be. It runs the right amount of times, and if I try... (3 Replies)

printf
PRINTF(3S)PRINTF(3S)NAME
printf, fprintf, sprintf - formatted output conversion
SYNOPSIS
#include <stdio.h>
printf(format [, arg ] ... )
char *format;
fprintf(stream, format [, arg ] ... )
FILE *stream;
char *format;
sprintf(s, format [, arg ] ... )
char *s, format;
DESCRIPTION
Printf places output on the standard output stream stdout. Fprintf places output on the named output stream. Sprintf places `output' in
the string s, followed by the character ` '.
Each of these functions converts, formats, and prints its arguments after the first under control of the first argument. The first argu-
ment is a character string which contains two types of objects: plain characters, which are simply copied to the output stream, and conver-
sion specifications, each of which causes conversion and printing of the next successive arg printf.
Each conversion specification is introduced by the character %. Following the %, there may be
- an optional minus sign `-' which specifies left adjustment of the converted value in the indicated field;
- an optional digit string specifying a field width; if the converted value has fewer characters than the field width it will be
blank-padded on the left (or right, if the left-adjustment indicator has been given) to make up the field width; if the field width
begins with a zero, zero-padding will be done instead of blank-padding;
- an optional period `.' which serves to separate the field width from the next digit string;
- an optional digit string specifying a precision which specifies the number of digits to appear after the decimal point, for e- and
f-conversion, or the maximum number of characters to be printed from a string;
- the character l specifying that a following d, o, x, or u corresponds to a long integer arg. (A capitalized conversion code accom-
plishes the same thing.)
- a character which indicates the type of conversion to be applied.
A field width or precision may be `*' instead of a digit string. In this case an integer arg supplies the field width or precision.
The conversion characters and their meanings are
dox The integer arg is converted to decimal, octal, or hexadecimal notation respectively.
f The float or double arg is converted to decimal notation in the style `[-]ddd.ddd' where the number of d's after the decimal point
is equal to the precision specification for the argument. If the precision is missing, 6 digits are given; if the precision is
explicitly 0, no digits and no decimal point are printed.
e The float or double arg is converted in the style `[-]d.ddde+-dd' where there is one digit before the decimal point and the number
after is equal to the precision specification for the argument; when the precision is missing, 6 digits are produced.
g The float or double arg is printed in style d, in style f, or in style e, whichever gives full precision in minimum space.
c The character arg is printed. Null characters are ignored.
s Arg is taken to be a string (character pointer) and characters from the string are printed until a null character or until the num-
ber of characters indicated by the precision specification is reached; however if the precision is 0 or missing all characters up to
a null are printed.
u The unsigned integer arg is converted to decimal and printed (the result will be in the range 0 to 65535).
% Print a `%'; no argument is converted.
In no case does a non-existent or small field width cause truncation of a field; padding takes place only if the specified field width
exceeds the actual width. Characters generated by printf are printed by putc(3).
Examples
To print a date and time in the form `Sunday, July 3, 10:02', where weekday and month are pointers to null-terminated strings:
printf("%s, %s %d, %02d:%02d", weekday, month, day, hour, min);
To print pi to 5 decimals:
printf("pi = %.5f", 4*atan(1.0));
